    Abstract: A method of forming a buried gate electrode prevents voids from being formed in a silicide layer of the gate electrode. The method begins by forming a trench in a semiconductor substrate, forming a conformal gate oxide layer on the semiconductor in which the trench has been formed, forming a first gate electrode layer on the gate oxide layer, forming a silicon layer on the first gate electrode layer to fill the trench. Then, a portion of the first gate electrode layer is removed to form a recess which exposed a portion of a lateral surface of the silicon layer. A metal layer is then formed on the semiconductor substrate including on the silicon layer. Next, the semiconductor substrate is annealed while the lateral surface of the silicon layer is exposed to form a metal silicide layer on the silicon layer.

    Abstract: An optical amplifier includes a passive waveguide region and an active waveguide region. The passive waveguide region is configured to receive an incident optical signal and adjust a mode of the optical signal. The active waveguide region is integrated to the passive waveguide region and configured to perform gain modulation on the optical signal received from the passive waveguide region by changing density of carriers in response to a current applied to the active waveguide region. Internal loss of the active waveguide region is adjusted to produce a resonance effect and thereby to increase bandwidth of the active waveguide. Therefore, the optical amplifier can have a wide bandwidth under a low-current condition.

    Abstract: The present invention provides a light emitting keypad having a very slim light guide film, and a light guide film for a keypad backlight. Particularly, a reflection layer is formed on a lower portion of the light guide film, resulting in more improved luminance. According to the present invention, the introduction of an EL sheet is eliminated, substantial slimness is achieved as compared with a direct illumination type keypad, high luminance is obtained by introducing a reflection layer even though a small number of light sources are used, and a light emitting surface can be provided for intensive light emission onto key regions of a keypad by forming a predetermined pattern on at least one surface of the light guide film.

    Abstract: A system and method for sound source separation. The system and method use a beamforming technique. The sound source separation system includes a windowing processor; a DFT transformer; a transfer function estimator; and a noise estimator. The system also includes a voice signal extractor that cancels individual voice signals, except an individual voice signal that is desired to be extracted among individual voice signals, from the integrated voice signals. The system further includes a voice signal detector that cancels a noise part provided through the noise estimator from a transfer function of an individual voice signal which is desired to be detected and extracts a noise-canceled individual voice signal. Even when two or more sound sources are simultaneously input, the sound sources can be separated from each other and separately stored and managed, or an initial sound source can be stored and managed.

    Abstract: An adaptive mode control apparatus and method for adaptive beamforming based on detection of a user direction sound are provided. The adaptive mode control apparatus includes a signal intensity detector that searches for signal intensity of each designated direction to detect signal intensity having a maximum value when a voice signal of each direction is input through at least one microphone; and an adaptive mode controller that compares the signal intensity having the maximum value detected through the signal intensity detector with a threshold value and determines whether to perform an adaptive mode of a Generalized Sidelobe Canceller (GSC) according to the comparison results. Therefore, a lack of control of adaptation of an adaptive filter of the conventional art is solved. That is, as one condition for guaranteeing performance of adaptive beamforming, adaptation of an adaptive filter is not performed when noise of a sound with a high autocorrelation is cancelled.
